Resumo: Purpose: To evaluate in vitro the shear bond strength of orthodontic accessories to porcelain, under different porcelain surface treatment protocols, and the resultant failure pattern after debonding. Methods: The sample consisted of 80 feldspathic porcelain discs, divided into 4 groups: Group 1 – 37% Phosphoric acid etching; Group 2 – 10% fluorhydric acid; Group 3 – 37% Phosphoric acid and silane application; Group 4 – 10% fluorhydric acid and silane application. The samples were submitted to the shear bond strength test in a universal test machine to record the maximum rupture force. Results: Group 1 showed lower results, and Group 4 presented higher results than the other tested groups. There was no statistical difference between Groups 2 and 3. Groups 1 and 3 presented exclusively adhesive failures between porcelain and resin, whereas Groups 2 and 4 showed cohesive failures in porcelain. Conclusion: The use of phosphoric acid followed by silane application was the best protocol for bonding orthodontic accessories to porcelain surfaces, since it was capable of resisting the forces applied during orthodontic treatment without causing irreversible failures in restorations.

Metodologia: A amostra foi composta de 80 pastilhas de porcelana feldspática, divididas em 4 grupos: Grupo 1 – Ácido fosfórico a 37%; Grupo 2 – ácido fluorídrico a 10%; Grupo 3 – ácido fosfórico a 37% e silano; Grupo 4 – ácido fluorídrico a 10% e silano. A amostra foi submetida a teste de cisalhamento em máquina de ensaios universal para registro da força máxima de ruptura. Resultados: O grupo 1 teve resultados inferiores aos demais grupos testados, bem como o grupo 4 apresentou resultados superiores. Não houve diferença entre os grupos 2 e 3. Os grupos 1 e 3 apresentaram falhas exclusivamente de caráter adesivo entre porcelana e resina, enquanto que nos grupos 2 e 4 registrou-se a ocorrência de falhas coesivas em porcelana. Conclusão: Conclui-se que a utilização de ácido fosfórico e silano representa o melhor protocolo de adesão de acessórios ortodônticos a superfícies de porcelana, uma vez que é capaz de resistir às forças aplicadas durante o tratamento ortodôntico sem causar falhas irreversíveis à restauração.EDIPUCRS - Editora Universitária da PUCRS2011-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articlein vitro studyapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/9736Revista Odonto Ciência; Vol. 27 No. 1 (2012); 47 - 51Revista Odonto Ciência; v. 27 n. 1 (2012); 47 - 511980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/9736/7686Guimarães, Magáli BeckLenz, Helen FernandesBueno, Rodrigo SalbegoBlaya, Micéli GuimarãesHirakata, Luciana Mayumiinfo:eu-repo/semantics/openAccess2013-11-11T11:36:13Zoai:ojs.revistaseletronicas.pucrs.br:article/9736Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T11:36:13Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
